WILLIAM S. KINSLEY, 0F READING, MASSACHUSETTS, ASSIGNOB TO THE RUSSELLCOMPANY, 015 BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

EXTRACTOR.

Application filed. June 3,

To all whom it may concern:

Be it known that I, WILLIAM S. KINsLEY, a citizen of the United States,and a resident of Reading, in the county of Middlesex and State ofMassachusetts, have invented an Improvement in Extractors, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

My invention relates to apparatus for treating fibrous material, such aswool, shoddy or the like in its raw state or when woven into a cloth,and particularly but not exclusively is concerned with extractionapparatus for removing water from such material.

My invention will be best understood from the following descriptionandaccompanying drawings of specific embodiments of invention selected forillustrative purposes, while the scope of my invention will be moreparticularly pointed out in the appended claims.

In the drawings Fig. l indicates diagrammatically an apparatus forsubjecting cloth to suction.

Fig. 2 is a detail of Fig.1 on an enlarged scale.

Fig. 3 is a fragmentary section on the line 3-3 of Fig. 2, and

Fig. 4 is a diagrammatic representation of my invention applied fortreating fibrous material in the raw state Referring to Fig.1 and to thepreferred embodiment of one type of my invention, I have indicated at 1a strip of cloth which is being fed from the roll 2 over a conduit 3,the guide pulleys 1 and the tension pulley 5 serving to maintain theproper tension on the cloth.

In the treatment of cloth, it is often necessary to subject the cloth'tothe action of water, which may be done as will be understood by thoseskilled in the art, at some place on the strip intermediate'the roll 2and conduitb. At the conduit 3 the water is removed from the cloth bysubjecting the cloth to suction.

To this end the conduit is provided with an orifice 6 in the form of alongitudinally extending slot of length suflicient toreach across thewidth of the strip. The interior of the conduit 3 is connected to anysuitable means for creating suction, for example,

to an exhaust blower. For holding the cloth against the orifice Iprovide a presser roll 7. In order that the presser roll mayautomatically adjust itself to irregularities in the thickness of thecloth the presser roll is made up in the form of a plurality of narrowdisks 8 which are in contact with each other and divide the disk into aplurality of relatively movable sections. These disks, which may be ofany suitable material, as for example, bronze, are each provided with anaxial perforation 9 through which extends a rod 10, the rod as will beobvious limiting the relative movement between the disks. At oppositeends the rod is carried by a fixed part of the apparatus.

Any suitable means may beprovided for holding the disks in contact asfor example a flange at each end of the rod one of which is shown at 11.

In Fig. 1 I have illustrated an arrangement for subjecting raw fibrousmaterial, such as wool or shoddy to suction, which may be done forexample, for the purpose of removing water or other liquid from suchmaterial.

Referring to Fig. 4, I have shown a conduit 8 having the longitudinalslot 6 and passing over the slot 6 in contact with the conduit I haveshown a belt conveyor 12 of pervious construction, for example, looselywoven cloth. The conveyor 12 is supported on pulleys 13, one of which aswill be obvious may be driven to cause the conveyor to progress.

Above the left hand pulley 13 I mountin any suitable manner a pulley 14over which passes a conveyor 15. The conveyor 15 has associatedtherewith any suitable mechanism or it leads fromany suitableinstrumentality either of which will act to cause the fibrous materialto take the form of a sheet 17 when it leaves the conveyor 15. As willbe obvious the conveyor 15 places the fibrous material on the conveyor12.

For pressing the fibrous material and the pervious conveyor 12 againstthe orifice 6 I may employ a presser roll 7 similar to that described inconnection with Figs. 1, 2 and 3.

1 It will be understood that I have disclosed apparatus for subjectingsheets of fibrous material both in the raw and fabricated state tosuction and further tha l have disclosed a presser roll which isconstructed to provide a cylindrical surface for pressing the fibrousmaterial toward the orifice and that this surface is constituted by theperipheries of the relatively movable disks 8, which results in theportions of the surface longitudimilly of the roll being relativelymovable to each other diametrically ot the roll.

Although I have described for purpose of illustration several speriiicembodiments of my invention, it is to be understood that I am not li dthereby to the particular details and arrangement of parts of theseembodiments but that wide deviations may be made therefrom withoutdeparting from the spirit of my invention.
